With NVIDIA clamping restrictions on graphics card makers' ability to make custom design PCBs for its flagship GeForce GTX TITAN GPU, the likes of GIGABYTE are opting for the next best thing - creating accessories that enthusiasts can mod their GTX TITAN graphics cards with, at the cost of product warranties. A little earlier this month, the company unveiled its WindForce 450W VGA cooler, which is capable of handling GTX TITAN. At a more recent event, it showed of G-Power, a supplementary voltage regulation module, which is similar in principle to EVGA EPower and ASUS Matrix PWM.

The device is a small PCB with high-capacity power leads on one-end, which need to be soldered on to the reference GeForce GTX TITAN PCB, and a combination of 24-pin ATX and 8-pin EPS connectors on the other. Between them is a 6+1 phase VRM, with components that appear similar to the ones used on GIGABYTE Ultra Durable 5 motherboards, consisting of 60A ferrite core chokes, International Rectifier PowIRstage IR3550 driver-MOSFETs, and International Rectifier IR3563A controller. The G-Power module stabilizes power on the GTX TITAN PCB, preventing voltage droop from breaking the overclock. There's no word on how GIGABYTE plans to sell these.

However GIGABYTE can always make an 8 phase model that can do 480A, otherwise this 6 phase is enough. The numbers listed are in amperes not watts, so this isn't power, just current.

It isn't a cheap rip off, the IR3550 provide the highest power density and are extremely expensive, however it prob will be cheaper as it is almost half the number of phases of the EVGA one, and it also doesn't have any extra VRM for the memory. Still its a pretty good contender. The GIGABYTE one also seems as if it takes in a 24-pin connector too, this would allow you to just hook up a PSU to the G-Power and not worry about loading its other rails perhaps(that is a just a guess, but maybe they have a system where using the 24-pin helps load the PSU so you can isolate that PSU from the rest of your system. .
